Answer 2

You have a system of two linear equations with two variables, x and y:

1. x + 2y = 6
2. 62x - 2y = 9

You can solve this system of equations using the method of your choice, such as substitution, elimination, or matrices. Here, I'll use the elimination method to solve for x and y:

First, add the two equations together to eliminate the variable "y":

(x + 2y) + (62x - 2y) = 6 + 9

This simplifies to:

63x = 15

Now, divide both sides by 63 to solve for x:

x = 15 / 63

You can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3:

x = 5 / 21

Now that you've found the value of x, you can substitute it back into either of the original equations to solve for y. Let's use the first equation:

x + 2y = 6

(5/21) + 2y = 6

Now, isolate the variable y:

2y = 6 - 5/21

2y = (126/21) - (5/21)

2y = 121/21

Now, divide both sides by 2 to solve for y:

y = (121/21) / 2

y = (121/21) * (1/2)

y = (121/42)

This is the solution to the system of equations:

x = 5/21 y = 121/42

You can simplify the fractions further if needed.
